DEVICE FOR EXHIBITION PURPOSES.

SPECIFICATION forming part of Letters Patent N o. 443,991, dated January6, 1891.

Application tiled April 28, 1890. Serial No. 349,793. (No model.) I

To @ZZ whom it may concern.-

Be it known that I, SIDNEY R. ELLIS, acitizen of the United States, anda resident of the city, county, and State of NewYork, have invented anew and useful Device for Exhibition or Stage Purposes, of which thefollowing is a specification.

My invention relates to improvements in devices for giving aquaticexhibitions, either in the open air or in buildings or upon the stage;and it consists of a mechanical whale which is constructed of wood ormetal, and which is furnished with tanks, into which water may beadmitted to sink the whale in the water, and with suitable devices bymeans of which it may be propelled and guided.

In the accompanying drawings, forming part of this specification, and inwhich similar letters of reference indicate similar parts throughout theseveral views, Figure 1 is a side elevation of my mechanical Whale; Fig.2, a longitudinal sectional elevation of the same 5 and Fig. 3, anenlarged transverse section on theline .fr Fig. 2.

The body A of the whale is constructed of wood or metal a, which issuitably braced by knees and ribs, (not shown,) and which is coveredwith a coating b of cork or some other Soft material.

Within the whale is placed the mechanism for driving and guiding it. Iprefer to propel the whale by electricity, and to this end I placeWithin the whale an electric motor B, to the armature of which I attacha shaft C, upon the end of which is a propeller D.

E is a storage-battery which furnishes the power for driving motor B.

Upon the shaft C is a pinion F, which meshes into and drives agear-wheel G, which is carried upon a shaft H, supported in suitablebearings in brackets I, which are secured to the body of the whale. Uponthis shaft are two collars J K, which are furnished with grooves jConnected with groove j in collar J is a lever L, the lower end of whichis attached to the lower jaw of the whale. This jaw works upon a pivotM, Fig. 2. As the shaft H and collar J are revolved, the upper end oflever L is caused to move back and forth, causingthelower jaw to openand close.

N is a lever, the lower end ot' which is pivoted at O and the upper endof which works in groove 7c in collar K. Attached to lever N is thepiston-rod of a pump P, which is connected with suitable pipes R, Fig.2, to the tanks T, Fig. 3, or with the Water in which the Whale oats.

S is a pipe leading from pump P to the nos trils of the whale. Therevolution of collar K causes lever N to be moved back and forth,operating the pump P, which throws a stream of water through thenostrils.

The whale is guided by moving its tail U, which is hinged to the body inany suitable manner, and which acts as a rudder. Atiller V is attachedto the tail and enters the body. To this tiller are attached the ends oftwo ropes W, which are guided by pulleys Y upon the inside of the whale.These ropes lead to a suitable steering apparatus Z in the front of thewhale.

c, Fig. 2, is an opening or window, through which the operator withinthe Whale may look, in order to guide it in its movements.

The tanks T are connected with the water in which the whale ioats bymeans of openings cl near their bottoms. e are valves, by means of whichthese openings may be opened or closed. Near the tops of the tanks T areopenings f to allow the escape of air while the tanks are being filled.

Upon the top of the whale is a trapdoor g, through which access may behad to its inte rior.

The tanks T may be of sufjicient size that when full of water the whalemay be completely submerged, and these tanks may be cleared of water bymeans of the pump P, which may pump the water out through the nostrilsor any other convenient place.

h, Figs. l and 2, isaiiexible water-tight covA ering, which covers thejoint between the body of the whale and the tail, and which preventswater from leaking in through this joint.

The body of the whale is covered with cork or some other suitablesubstance b, so that it can be speared or harpooned without injury.

Z, Figs. 1 and 3, are ins of the wha1e,which are attached to its sides,and which are immovable.

IOO

Having thus described my invention, I claim-` ll. The herein-describedautomatic whale, consisting of a Wood or metal body covered with cork orsome other suitable substance and furnished with devices, substantiallyas described, for propelling and guiding it.

2. The combination, in an automatic Whale, of thebody furnished withwater-tanks, as described, and openings and Valves for adinittng Watertothe tanks, apurnp connected with said tanks and With the nostrils ofthe Whale, and devices for operating said pump,
